STUDY OF DIFFERENT PROPERTIES AND APPLICATIONS OF POLY LACTIC-CO-GLYCOLIC ACID (PLGA) NANOTECHNOLOGY: AN OVERVIEW

In past decades poly lactic-co-glycolic acid (PLGA) has been one of the most attractive polymeric candidates used to fabricate devices for diagnostics and other applications of clinical and basic science research, including vaccine, cancer, cardiovascular disease, and tissue engineering. In addition, PLGA and its co-polymers are important in designing nanoparticles with desired characteristics such as biocompatibility, biodegradation, particle size, surface properties, drug release and target ability and exhibit a wide range of erosion times. PLGA has been approved by the US FDA for use in drug delivery. This article represents the more recent successes of applying PLGA-based nanotechnologies and tools in these medicine-related applications, and factors affecting their degradation and drug release. It focuses on the possible mechanisms, diagnosis and treatment effects of PLGA preparations and devices.
